The study represents an approach to improving the annual lighting and primary energy performance of a residential building in temperate-humid and hot-dry Mediterranean climates in Turkey by simulation-based optimization method. In this context, five design variables and sixty four options including façade orientation, window size and configuration, window-to-wall ratio, thermo-physical properties of glazing, and light reflectance value of walls are investigated. The global cost of interior lighting system proposal and passive design strategies are calculated accordingly. Compared to the reference building, we achieved 26.5 - 27.6 % savings in lighting energy, 8.5 - 8.9 % in global costs and 10.5 - 12.4 % in primary energy as well as 9.4 - 10.6 % reduction in carbon emissions for the optimal solutions depending on the climate zone, respectively. Daylight performance of sample living rooms is also evaluated with climate-based daylight modelling (CBDM) metrics for the base case and optimal solutions.
